Backlinks are important for both search engines and end users. For the search engines, it helps them determine how authoritative and relevant your site is on the topic that you rank for. Furthermore, backlinks to your website are a signal to search engines that other external websites are endorsing your content. If many sites link to the same webpage or website, search engines can interpret that content is worth linking to, and therefore also worth ranking higher on a SERP (search engine results page). For many years, the quantity of backlinks was an indicator of a page’s popularity. But today algorithms like Google's Penguin update, were created to help with other ranking factors; pages are ranked higher based on the quality of the links that they are getting from external sites and less on quantity.

Marketing managers need to be conversant in every element of a marketing campaign, and considering the importance of an Internet presence in any marketing plan today, this means having a clear understanding of Internet marketing from start to finish.

If you are going to use SEM, you must build the costs of using this form of marketing into your cash-flow forecasts and the prices you’re charging for your work.

Spending $3,000 a month to land $3,500 of business, on the other hand, is likely to be a disaster for your business’s ability to trade effectively in the long term.
It’s not enough to decide you’re going to make a video for your business marketing. There are three main and very distinct formats that each come with different restrictions and advantages: live, short and long formats. Since they all serve a different purpose, try using a mix of all three in your overall marketing strategy, or even within one campaign.
This guide is designed for you to read cover-to-cover. Each new chapter builds upon the previous one. A core idea that we want to reinforce is that marketing should be evaluated holistically. What you need to do is this in terms of growth frameworks and systems as opposed to campaigns. Reading this guide from start to finish will help you connect the many moving parts of marketing to your big-picture goal, which is ROI.
The majority of web traffic is driven by the major commercial search engines, Google, Bing, and Yahoo!. Although social media and other types of traffic can generate visits to your website, search engines are the primary method of navigation for most Internet users. This is true whether your site provides content, services, products, information, or just about anything else.
